Hey Frontios, welcome. Some patients use it to treat the tremors and muscle spasms associated with Parkinson's and MS so I'd say there is a good chance that cannabis could help you. I don't know how much you actually know about cannabis (if you don't know much, this is a great place to learn), but there are different types and strains of the plant. A strain which is primarily indica is known to have more of a body stone, which means you're whole body feels very relaxed.

In my opinion, for your condition, a strain that is from the indica family or one which is mostly indica would probably help you. If you live in a location where marijuana is acceptable for med purposes you should discuss this with your doctor.
